CHARLES KELLY, OF BOSTON, MASSACHUSETTS, ASSIGNOR T0 SPRAY ENGINEERING COMPANY, 0F BOSTON, MASSACHUSETTS, A. CORPORATION OF MASSACHUSETTS.

a SPRAY Application filed November To all whom t may concern.'

Be 'it known that I, CHARLES KELLY, a citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented new and useful Improvements in Spray Nozzles, of which the following is a speciication.

This invention relates to a spray nozzle adapted for connection with a water conduit, and having a receiving` portion of relatively large diameter, a delivering portion or outlet of smaller diameter coaxial with the receiving portion, and defleotors within the receiving portion, having faces which are inclined relatively to the longitudinal axis of the nozzle, and adapted to impart a gyrating or whirling motion to a stream of water fiowing through the nozzle, so that the stream emerges from the outlet more or less subdivided into spray.

Heretofore, so far as I am aware, the deflectors have always been iiXed or nonadjustable, and have been incapable of adjustment, causing their faces to stand parallel with the longitudinal axis of the nozzle when it is desired to flushy the nozzle and remove obstructions between the deflectors.

One object of my invention is to obviate this defect. Another object is to enable the portion of the nozzle to which the deflectors are attached to be turned, to either close the nozzle, or to reverse the deflectors withrelation to a stream flowing through the nozzle.

To these and other related ends the invention is embodied in the improvements which I will now proceed to describe and claimll Of the accompanying drawings forming a part 'of this specification,-

Figure 6 is a View similar to a portion of Figure 2, showing one defiector in its deflecting position.

Figure 7 is a view similar to Figure 6, showing the deflector adjusted to permit flushing of the nozzle.

Figures 8 and 9 are end views of the deflector-carrying portion of the nozzle, without the delector.

Figures 1() and 11 are, respectively, a side view and end view of one of the deflectorsA Figure 12 is a sectional view, showing a different embodiment of the invention.

The same reference characters indicate the sante parts in all of the figures.

In the preferred embodiment of the invention shown by Figures 1 to 8, inclusive, the nozzle is constructed as a stop cock, and includes, first, a casing portion 5, adapted at one end, as by an internally threaded socket 6, for attachment to a nipple forming a part of a water conduit, and provided with a circular plug chamber 7, and with an outlet 8, and, secondly, a dellector-carrying portion 9, formed as a plug adapted to turn in said chamber, and provided at one end with a wrench-engaging portion 10, and at the other end with a securing washer 11 attached by screws 11a.

'Ihe deilector-carrying portion 9, which, for convenience, I will call the plug, has a receiving portion 12, of relatively large diameter, and an outlet portion 13 of smaller diameter, and coaxial with the receiving portion 12.

'Ihe plug is provided with a plurality of radial deflectors adjustably engaged with and projecting inwardly from the wall of the receiving portion 12, and having deflecting'faces which are adapted to stand either in planes inclined relatively to the longitudinal airis of the nozzle, to cause a whirling motion of water flowing through the nozzle, or in planes parallel with said axis to permit the removal of obstructions from the deflectors by the water. As mostclearly shown in Figs. 2 and 3, the several deflectors are located wholly and in all positions out of the axial line of the nozzle.

In the preferred embodiment of the invention shown by the drawings, the wall of the receiving portion 12 is provided at its` inner portion with a plurality of tapped radial sockets 16, of Which there may be any desired number. Sonie of the sockets extend through the ends of the plug, as shown by Figures 2 and 3, and others extend through the periphery of the plug, as

yall of the receiving portion 12, and are adapted, by suitable adjust-ments of the shank port-ion 17, to stand either in planes u inclined relatively to the longitudinal axis oi'the nozzle, as shownby Figures 2, 3, 4, 5 and 6, to cause a ivhirlin motionv of the Watenor in planes paralle with said axis, shown by lFig-ure 7', to permit the removal of obstructions between the deilectors by the rvaten'each shank 17 being prov-ided with a slet 20, adapted to be engaged by a screw-driver, or other like tool.

The detlectors may be grouped in series, as shoivn by Figures 2,' 3, 4L and 5, the deflectors of one s'eriesvbeing in staggered relation to those of the adjacent series, so that Water flowing undeiiected between the deliectors of the ii-rst or lower series, is deflected by the de flectors ofthe next or outer series.

It Will be seen that each delector is capable of beingadjusted to vary the inclination of its faces 19, and thus vary the number of convolutions imparted to the water in its passage through the nozzle.

The *plug 9 may be turned to the position shown by Figure 4l, to close the nozzle, or to the position shown by Figure 5, to reverse the relative positions of the receivingv portion 12, and outlet portion 13, so thatwater will enter the plug at the outlet portion 13, and force obstructions therein through the largerv receiving portion 12. rllhe plug may also be turned toV various intermediate positions to simultaneously vary the inclination of the deflect-ors.

The invention as pointed out by some of the appended claims may be embodied either as above described, or in aV nozzle not adapted .to be closed, the deiieotors rbeing adjustahly secured `by the means described to a nozzle having a receiving portion 12a and an outlet portie-11131, as shown by Ph'gure 12.
